Flange

Flange, also known as flange disc or flange. Flanges are parts that are interconnected between shafts and shafts for connections between pipe ends; There are also flanges used on the inlet and outlet of equipment for the connection between two devices, such as reducer flanges. Flange connection or flange joint refers to the detachable connection of flange, gasket and bolt as a set of combined sealing structure. Pipe flange refers to the flange used for piping in the pipeline device, and the inlet and outlet flange of the equipment used in the equipment. There are holes in the flange, and the bolts make the two flanges closely connected. The flange is sealed with a gasket. Flange split threaded connection (wire connection) flange, welded flange and clip flange. The flanges are used in pairs, the low-pressure pipeline can use the wire flange, and the welded flange is used for pressures above four kilograms. A gasket is added between the two flanges and then bolted to tighten. The thickness of the flange for different pressures is different, and the bolts they use are also different. Water pumps and valves, when connected with pipelines, the parts of these equipment and equipment are also made into corresponding flange shapes, also known as flange connections. All the connecting parts that are closed at the same time by bolting around the perimeter of the two planes are generally called "flanges", such as the connection of ventilation ducts, this type of parts can be called "flange parts". But this connection is only a part of the equipment, such as the connection of flange and pump, it is not good to call the pump "flange parts". Relatively small ones such as valves can be called "flange parts".
